My installation of Ubuntu is having trouble with my kernel buildbecause I disabled support for sysctl:

warning: process `ls' used the removed sysctl system callwarning: process `touch' used the removed sysctl system callwarning: process `touch' used the removed sysctl system callwarning: process `evms_activate' used the removed sysctl system callwarning: process `alsactl' used the removed sysctl system call

I am curious whether the use of sysctl indicates a problem in theseprocesses. What is the benefit of offering disabling sysctl support?
